Title: MINOS results, progress and future prospects

Abstract

The MINOS long baseline experiment has been collecting neutrino beam data since March 2005 and has accumulated 3 x 10{sup 20} protons-on-target (POT) to date. MINOS uses Fermilab's NuMI neutrino beam which is measured by two steel-scintillator tracking calorimeters, one at Fermilab and the other 735 km downstream, in northern Minnesota. By observing the oscillatory structure in the neutrino energy spectrum, MINOS can precisely measure the neutrino oscillation parameters in the atmospheric sector. From analysis of the first year of data, corresponding to 1.27 x 10{sup 20} POT, these parameters were determined to be |{Delta}m{sup 2}{sub 32}| = 2.74{sup +0.44}{sub -0.26} x 10{sup -3} eV{sup 2}/c{sup 4} and sin{sup 2}(2{theta}{sub 23}) > 0.87 (68% C.L.). MINOS is able to measure the neutrino velocity by comparing the arrival times of the neutrino beam in its two detectors. Using a total of 473 Far Detector events, (v -c)/c = (5.1{+-}2.9)x10{sup -5} (68% C.L.) was measured. In addition, we report recent progress in the analysis of neutral current events and give an outline of experimental goals for the future.

  • The MINOS experiment uses the intense NuMI beam created at Fermilab and two magnetized tracking calorimeters, one located at Fermilab and one located 735 km away at the Soudan Mine in Minnesota, to make precise measurements of {nu}{sub {mu}} disappearance oscillation parameters. We present recent results from the first two years of NuMI beam operations, including the precise measurement of the atmospheric neutrino oscillation parameters and the search for sterile neutrinos. Future prospects for MINOS will also be discussed, including an improved limit on the {theta}{sub 13} mixing angle by searching for {nu}{sub e} appearance in the {nu}{sub {mu}} beam.
  • Goals of the recently repaired Solar Maximum Mission Observatory are outlined, including continued emphasis on diagnosing impulsive phase of flares, studies of prominence and coronal plasmas, solar cycle variations of flares, the corona and solar irradiance, and comets. Some preliminary observations taken after the repair are shown, particularly of the X13 flare of April 1984. 9 references.
  • The long history of petroleum operations in the southeastern area of the Pannonian basin (eastern Yugoslavia) relates to successful explorations using state-of-art tools in geology, geophysics, and geochemistry, as well as in deep drilling. The paper will discuss chronologically past explorations and problems encountered in its specific stages. A comprehensive petroleum geological overview will highlight the most important features of the 30,000-km{sup 2} exploration area, including issues such as oil and gas origin, occurrence of source, reservoir, and cap rocks, hydrocarbon migration and accumulation etc. Particular attention will be devoted to the description of the applied exploration techniques and resultsmore » obtained on this very interesting hydrocarbon-bearing area. Due space will be given to the application of the recent developments for assessing the potential of the deep buried, comparatively unknown targets situated in extremely complex environments under adverse temperature and pressure conditions.« less
